I believe we have had this discussion before, but I'll iterate my 
beliefs in favour of allowing direct root access again:

- - Key-based root logins are quite secure.  I don't see any reason why 
key-based root login would be any less secure than permitting a user 
login followed by an sudo.

- - Password management is a bitch.  I don't remember passwords for 
about half the accounts I have.  Using a key-based root login, I 
don't need to remember those passwords either.  If you take the sudo 
route, every user has to remember each password for each account, 
unless you take the deprecated route of reusing passwords (or 
*horrors* allow sudo without password).

- - With a little bit of configuration, it's easy to figure out which 
key was used to login to an account; the audit trail can be managed 
that way.

- - Managing which users have access to which root accounts is trivial 
this way: just add or delete their keys from .ssh/authorized_keys[2].

Of course, ideally you could use a combination of user-based and 
key-based logins: allow users to login any which way they want, then 
only allow key-based root ssh from localhost.  Hmm, that's an idea 
worth exploring...
